BOX FASTENER Application filed September T 0 all whom it may concern:

Be it known that I, Lnwrs D. YOUNG, a citizen of the United States, residing at Providence, in the county of Providence and State of Bhode Island, have invented new and useful Improvements in Box Fasteners, of which the following is a specification.

This invention relates to certain new and useful improvements in box fasteners and more particularly relates to fasteners of the type which are formed of bendable tongues or fingers that are projected through slits provided therefor in the box lid and which are then bent over to lie in superimposed relation to the lid.

The primary object of the invention is to provide improved fingers which are possessed of increased longevity, i. e., which are capable of being bent into and out of lid securing position a large number of times without breaking.

A further object of the invention is to provide means for the aforementioned purpose which also acts to more effectively secure the lid in position and which at the same time can be easily bent and also bent along a fixed line throughout the life of the fingers.

In the drawings:

Figure l, is a longitudinal sectional view of the invention ailixed to a box;

Figure 2, is an end elevation, the lid being removed;

Figure 3, is a section on line 3-3 of F igure 2, and

Figure 4-, is a detail plan view of one of the fasteners.

ln proceeding in accordance with the pres ent invention the fasteners employed are formed of blanks as depicted in Figure 4., wherein the tongues or fingers 1, have base spurs 2 that are clinched to the box or body B, so that the upper or free end portions of the fingers project, as customary, for a distance above the upper edges of the box ends, as illustrated in Figure 2.

The present invention resides in the formation of two spaced transverse rows of punched or struck-out teats or knobs 3, each teat or knob being hollow or of concaveconvex crosssection, or otherwise stated, of cup-like form. These two rows of knobs are arranged in reverse order, i. e., the convex sides of the knobs of the lower row face outwardly, while the convex sides of the as, 1921. Serial No. 503,191.

knobs of the upper row face inwardly, or downwardly when the fingers are in lid securing position. The space between the two rows of knobs occurs at points alined with the upper edge of the box 33 and forms a 0 line of hinging or bending on or about which the free ends of the fingers are moved.

These knobs greatly strengthen the fingers or tongues on lines transversely thereof, and in so doing render the parts of the fingers in the space between the knobs relatively weakened so as to readily permit of bending of the fingers. By facing the knobs in opposite directions as shown and above described, the bending is facilitated, since same occurs toward the concave sides of the lower row. In addition, the line of bend is thus positively confined to the space between the two rows of knobs, whereas heretofore the lines of bend have been indeterminate, relatively speaking and widely scattered, resulting in rapid distortion of the fingers and either breakage thereof, or impairment of efii ciency and difficult straightening, in an endeavor to remove the numerous kinks resultant from bending along various lines.

In further addition, it will be noted that the knobs of the lower row afford projection which somewhat bite into or frictionally engage against the flange of the top T,while the knobs of the upper row are similarly engaged with the upper face of the top T, so that the latter is more efi'ectively held in place.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a box fastener, a tongue having means at one end for securing same to a box and having a pair of spaced transverse rows of punched knobs of concavo-convex crosssection disposed intermediate its ends, the convex sides of the knobs of the rows facing in opposite directions and the space between said rows being disposed to aline with the top edge of the box.

2. In a box fastener, a tongue having means at one end for securing same to a box and having a pair of spaced transverse rows of punched knobs disposed intermediate its ends, the space between said rows being disposed to aline with the top edge of the box.

3. In a box fastener, a body, a bendable lid securing tongue attached at one end wardly therefrom to define a line on Which the tongue bends and being arranged so that one of the means engages in the flange and 15 the other engages in and on top of the lid;

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
